Abstract (en)

[origin: WO2021092211A1] Systems, methods and software for scanning an ocular structure of an eye are provided. A method includes projecting a light onto the ocular structure, and scanning, by natural movements of the living eye, the light in a region of the living eye. Applicable ocular structures can include an ocular surface, a cornea, a sclera, an iris, a crystalline lens, an ocular fundus, a retina, a choroid, and a vitreous humor. A system includes a light source to create light, and optics to focus the light from the light source onto the ocular structure and to collect secondary light coming from the eye towards a detector. The system also includes a tracking system to register positions of the eye at different times, and a computer system to receive signals coupled from the tracking system representative of eye positions at different times and associate the signals with the tracking position.
